----

Or with Curses interface:

[source,shell]
----
ccmake ..
----

// TRANSLATION MISSING
[[tests]]
==== Tests

Following packages are *required* to compile tests:

* libcpputest-dev
* C++ compiler

Tests must be enabled when compiling WeeChat:

[source,shell]
----
cmake .. -DENABLE_TESTS=ON
----

They can be launched after compilation from the build directory:

[source,shell]
----
ctest -V
----

[[git_sources]]
=== Sorgenti Git

Attenzione: i sorgenti Git sono per gli utenti avanzati: potrebbero non
compilare o essere instabili. Siete avvisati!

Per ottenere i sorgenti Git, dare il comando:

[source,shell]
----
git clone https://github.com/weechat/weechat.git
----

Poi seguire le istruzioni per i sorgenti (consultare
<<source_package,sorgenti>>).

[[report_crashes]]
=== Segnalare gli errori

Nel caso in cui si verifichino errori, o si desideri segnalare qualsiasi errore
futuro di WeeChat, è necessario:

// TRANSLATION MISSING
* compile with:
** informazioni di debug (o installare il pacchetto binario con le informazioni di debug)
// TRANSLATION MISSING
** address sanitizer (optional)
* abilitare i file _core_ sul proprio sistema
* installare gdb

// TRANSLATION MISSING
[[debug_build]]
==== Debug build

Se si compila con CMake:

[source,shell]
----
cmake .. -DCMAKE_BUILD_TYPE=Debug
----

// TRANSLATION MISSING
[[address_sanitizer]]
==== Address sanitizer

// TRANSLATION MISSING
You can additionally enable the address sanitizer, which causes WeeChat to
crash immediately in case of problem:

[source,shell]
----
cmake .. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-fsanitize=address -DCMAKE_CXX_FLAGS=-fsanitize=address -DCMAKE_EXE_LINKER_FLAGS=-fsanitize=address
----

// TRANSLATION MISSING
[CAUTION]
You should enable address sanitizer only if you're trying to cause a crash,
this is not recommended in production.

// TRANSLATION MISSING
Then once compiled and installed, you must run WeeChat like this:

[source,shell]
----
ASAN_OPTIONS="detect_odr_violation=0 log_path=asan.log" weechat
----

// TRANSLATION MISSING
In case of crash, the backtrace is in file `asan.log`.

[[core_files]]
==== File core

// TRANSLATION MISSING
To enable _core_ files, you can use option
<<option_weechat.startup.sys_rlimit,weechat.startup.sys_rlimit>>:

----
/set weechat.startup.sys_rlimit "core:-1"
----

// TRANSLATION MISSING
For WeeChat ≤ 0.3.8 or if you want to enable core files even before WeeChat
starts, you can use `ulimit` command.

Ad esempio su Linux con la shell _bash_, aggiungere questa riga al proprio
`~/.bashrc`:

[source,shell]
----
ulimit -c unlimited
----

Oppure impostare una dimensione massima:

[source,shell]
----
ulimit -c 200000
----

[[gdb_backtrace]]
==== Ottenere un backtrace con gdb

// TRANSLATION MISSING
When WeeChat crashes, your system will create a file _core_ or _core.12345_
(_12345_ is process id) if the <<core_files,option is enabled>>.
Questo file viene creato nella directory in cui è in esecuzione WeeChat (e
*non* la directory dove WeeChat è installato!).

// TRANSLATION MISSING
[NOTE]
On some systems like Archlinux, core dumps could be in another directory like
_/var/lib/systemd/coredump_ and you must use the command `coredumpctl` to read it. +
For more information, see this
https://wiki.archlinux.org/title/Core_dump[wiki page ^↗^^].

Ad esempio, se _weechat_ è installato in _/usr/bin/_ ed il file _core_
si trova in _/home/user/_, allora eseguire gdb con questo comando:

[source,shell]
----
gdb /usr/bin/weechat /home/user/core
----

All'interno di gdb, usare il comando `bt full` per visualizzare
il backtrace. Verrà mostrato qualcosa di simile a questo:

----
(gdb) set logging file /tmp/crash.txt
(gdb) set logging on
Copying output to /tmp/crash.txt.
(gdb) bt full
#0  0x00007f9dfb04a465 in raise () from /lib/libc.so.6

        tv_time = {tv_sec = 1272693881, tv_usec = 212665}
        ptr_hook = 0x2811f40
        next_hook = 0x0
#6  0x000000000041b5b0 in gui_main_loop ()
    at /some_path/src/gui/curses/gui-curses-main.c:319
        hook_fd_keyboard = 0x173b600
        tv_timeout = {tv_sec = 0, tv_usec = 0}
        read_fds = {fds_bits = {0 <repeats 16 times>}}
        write_fds = {fds_bits = {0 <repeats 16 times>}}
        except_fds = {fds_bits = {0 <repeats 16 times>}}
        max_fd = <value optimized out>
----

Bisogna riportare l'errore agli sviluppatori, e specificare quale azione ha causato
l'errore.

Grazie per il vostro aiuto!

[[debug_running_weechat]]
==== Debug di WeeChat durante l'esecuzione

Per eseguire il debug di un'istanza di WeeChat in esecuzione (ad esempio se
WeeChat sembra sia bloccato), è possibile usare gdb con l'id del processo
(sostituire _12345_ con il PID del processo weechat):

[source,shell]
----
gdb /usr/bin/weechat 12345
----

Poi, come per un crash, usare il comando `bt full`:

----
(gdb) bt full
----

[[running_weechat]]
== Esecuzione di WeeChat

Per avviare WeeChat, digitare questo comando:

[source,shell]
----
weechat
----

// TRANSLATION MISSING
When you run WeeChat for the first time, the default configuration files are
created in _~/.config/weechat_ with default options and values
(see <<files_and_directories,Files and directories>>).

// TRANSLATION MISSING
[[command_line_options]]
=== Command line options

include::includes/cmdline_options.it.adoc[tag=standard]

// TRANSLATION MISSING
Some extra options are available for debug purposes only:

// TRANSLATION MISSING
[CAUTION]
Do *NOT* use any of these options in production!

include::includes/cmdline_options.it.adoc[tag=debug]

// TRANSLATION MISSING
[[environment_variables]]
=== Environment variables

Some environment variables are used by WeeChat if they are defined:

[width="100%",cols="1m,6",options="header"]
|===
| Name                 | Description
| WEECHAT_HOME         | The WeeChat home (with configuration files, logs, scripts, ...). Same behavior as <<build,CMake option>> `WEECHAT_HOME`.
| WEECHAT_PASSPHRASE   | The passphrase used to decrypt secured data.
| WEECHAT_EXTRA_LIBDIR | An extra directory to load plugins (from the "plugins" directory in this path).
|===

// TRANSLATION MISSING
[[colors_support]]
=== Colors support

WeeChat può usare fino a 32767 coppie di colore per visualizzare il testo nelle barre e
nell'area di chat(il terminale deve supportare 256 colori per essere utilizzati in WeeChat).

In base al valore della variabile di ambiente _TERM_, potrebbero verificarsi i
seguenti limiti per i colori in WeeChat:

[width="75%",cols="8,>3,>3",options="header"]
|===
| $TERM                                  | Colori | Coppie
| "rxvt-unicode", "xterm", ...           |     88 |  32767
| "rxvt-256color", "xterm-256color", ... |    256 |  32767
| "screen"                               |      8 |     64
| "screen-256color"                      |    256 |  32767
| "tmux"                                 |      8 |     64
| "tmux-256color"                        |    256 |  32767
|===

È possibile eseguire `weechat --colors` o utilizzare il comando `/color` in
WeeChat per visualizzare i limiti del proprio ambiente.

Alcuni valori raccomandati per _TERM_ se si desiderano 256 colori:

* con screen: _screen-256color_
// TRANSLATION MISSING
* under tmux: _screen-256color_ or _tmux-256color_
// TRANSLATION MISSING
* outside screen/tmux: _xterm-256color_, _rxvt-256color_, _putty-256color_, ...

[NOTE]
Potrebbe essere necessario installare il pacchetto "ncurses-term" per usare
questi valori nella variabile _TERM_.

Se si sta utilizzando screen, è possibile aggiungere questa riga al
proprio _~/.screenrc_:

----
term screen-256color
----

// TRANSLATION MISSING
If your _TERM_ variable has wrong value and that WeeChat is already running,
you can change it with these two commands:

----
/set env TERM screen-256color
/upgrade
----

// TRANSLATION MISSING
[[files_and_directories]]
=== Files and directories

[[xdg_directories]]
==== XDG directories

WeeChat uses XDG directories by default (according to the
https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html[XDG Base Directory Specification ^↗^^]). +
A single home directory for all files can be forced by CMake option `WEECHAT_HOME`,
the environment variable `WEECHAT_HOME` or the command-line option `-d` / `--dir`.

When a single WeeChat home directory is not forced, XDG directories are used
and set like this:

[width="100%",cols="1,2m,5",options="header"]
|===
| Directory | Default value            | Fallback value if $XDG_XXX is not defined
| config    | $XDG_CONFIG_HOME/weechat | `$HOME/.config/weechat`
| data      | $XDG_DATA_HOME/weechat   | `$HOME/.local/share/weechat`
| cache     | $XDG_CACHE_HOME/weechat  | `$HOME/.cache/weechat`
| runtime   | $XDG_RUNTIME_DIR/weechat | Same as _cache_ directory
|===

The configuration files are created with default values the first time you run WeeChat.

[[weechat_directories]]
==== WeeChat directories

The WeeChat directories are:

[width="100%",cols="1m,3",options="header"]
|===
| Path ^(1)^              | Description

| ~/.local/share/weechat/ | WeeChat data files: logs, scripts, scripts data, xfer files, etc.
|    logs/                | Log files (one file per buffer).
|    python/              | Python scripts.
|       autoload/         | Python scripts auto-loaded on startup ^(2)^.
|    perl/                | Perl scripts.
|       autoload/         | Perl scripts auto-loaded on startup ^(2)^.
|    ruby/                | Ruby scripts.

[IMPORTANT]
It is *not recommended* to edit configuration files by hand because WeeChat
may write them at any time (for example on <<command_weechat_quit,/quit>>)
and after any change you must run the command <<command_weechat_reload,/reload>>
(with the risk of losing other changes that were not yet saved with
<<command_weechat_save,/save>>). +
You can use the command <<command_weechat_set,/set>>, which checks the value
and applies immediately the changes.

// TRANSLATION MISSING
[[upgrade]]
== Upgrade

If a new stable version of WeeChat is released, this is time for you to
switch to this version.

First of all, you must install the new version of WeeChat, either with your
package manager or by compiling yourself, so that the `weechat` binary and all
required files are in the same paths. +
This can be done while WeeChat is running.

// TRANSLATION MISSING
[[upgrade_command]]
=== Upgrade command

WeeChat can restart the new binary, in place, using the
<<command_weechat_upgrade,/upgrade>> command: the buffer contents and non-TLS
connections are preserved. +
The TLS connections are lost during upgrade and are restored automatically
after the upgrade (reload of TLS sessions is currently not possible
with GnuTLS).

The command can also be used if you have to restart the machine, for example
to upgrade the kernel or to move your WeeChat to another machine:

----
/upgrade -quit
----

This saves the current state in `*.upgrade` files. You can then either reboot
or move the whole WeeChat directories (config, data, cache) to another machine,
and restart WeeChat later with this command:

[source,shell]
----
weechat --upgrade
----

// TRANSLATION MISSING

[[restart_upgrading_notes]]
==== Upgrading notes

// TRANSLATION MISSING
After an upgrade, it is *strongly recommended* to read the file
https://github.com/weechat/weechat/blob/main/UPGRADING.md[UPGRADING.md ^↗^^]
which contains important information about breaking changes and some
manual actions that could be required.

// TRANSLATION MISSING
You must read the versions between your old (excluded) and your new version (included). +
For example if you switch from version 4.0.0 to 4.3.0, you must read versions
4.0.1 to 4.3.0.

[[restart_configuration_upgrade]]
==== Configuration upgrade

WeeChat has an automatic upgrade of configuration files (`*.conf`):

* new options are silently added with default value
* obsolete options are automatically discarded and WeeChat displays a warning
  with the value read from file.

Example of warning when an option has been removed:

----
=!= Attenzione: /home/user/.config/weechat/sec.conf, riga 15: opzione sconosciuta per la sezione "crypt": passphrase_file = ""
----

That means the option `sec.crypt.passphrase_file` has been removed, and you
had value set to empty string, which was the default value in the previous version
(in this case no manual action is required).

to customize <<buffers_and_windows,buffers and windows>>,
and <<command_weechat_layout,/layout>> to name, save and restore the screen layout
and the association between windows and buffers.

[[command_line]]
=== Riga di comando

La riga di comando di WeeChat (nella parte inferiore della finestra) consente di
inserire i comandi o di inviare del testo sul buffer.

[[command_line_syntax]]
==== Sintassi

I comandi iniziano con il carattere "/", seguito dal nome del comando. Ad esempio,
per consultare un elenco di opzioni:

----
/set
----

Il testo inviato ad un buffer è qualsiasi testo che non comincia con
il carattere "/". Per esempio, per inviare il testo _ciao_ sul buffer
attivo:

----
ciao
----

Ad ogni modo, è possibile iniziare con il carattere "/", aggiungendone
poi un altro. Ad esempio, per inviare il testo `/set` sul buffer attivo:

----
//set
----

[[command_line_colors]]
==== Codici colore

Per alcuni plugin come IRC, è possibile usare codici colori ed attributi,
come segue (digitare kbd:[Ctrl+c] poi la lettera che segue, con il valore
opzionale):

[width="100%",cols="1,2",options="header"]
|===
// TRANSLATIION MISSING
| Key                    | Description
| kbd:[Ctrl+c], kbd:[b]  | testo in grassetto.
| kbd:[Ctrl+c], kbd:[c],
  kbd:[xx]               | colore del testo `xx` (consultare la lista di colori che segue).
| kbd:[Ctrl+c], kbd:[c],
  kbd:[xx], kbd:[,],
  kbd:[yy]               | colore del testo `xx` e di sfondo `yy` (consultare la lista di colori che segue).
// TRANSLATION MISSING
| kbd:[Ctrl+c], kbd:[d],
  kbd:[xxxxxx]           | Text color `xxxxxx` (RGB as hexadecimal, for example `FF0000` for red).
// TRANSLATION MISSING
| kbd:[Ctrl+c], kbd:[d],
  kbd:[xxxxxx], kbd:[,],
  kbd:[yyyyyy]           | Text color `xxxxxx` and background `yyyyyy` (RGB as hexadecimal).
// TRANSLATION MISSING
| kbd:[Ctrl+c], kbd:[i]  | italic text.
| kbd:[Ctrl+c], kbd:[o]  | disabilita colori ed attributi.
// TRANSLATION MISSING
| kbd:[Ctrl+c], kbd:[s]  | Strikethrough text (displayed as half bright in ncurses interface because strikethrough is not supported).
| kbd:[Ctrl+c], kbd:[v]  | video inverso (inverte il colore del testo con quello di sfondo).
| kbd:[Ctrl+c], kbd:[_]  | testo sottolineato.
|===

[NOTE]
// TRANSLATION MISSING
The same code (without number for kbd:[Ctrl+c], kbd:[c] and kbd:[Ctrl+c], kbd:[d])
can be used to stop the attribute.

I codici colore per kbd:[Ctrl+c], kbd:[c] sono:

include::{autogendir}/autogen_user_irc_colors.it.adoc[tag=irc_colors]

// TRANSLATION MISSING
[NOTE]
To show all available colors in your terminal, you can do `/color` then
kbd:[Alt+c] in WeeChat or run this command in terminal: `weechat --colors`.

Esempio: visualizza "ciao Alice!" con "ciao" scritto in blu chiaro grassetto
e "Alice" in rosso chiaro sottolineato:

----
^Cc12^Cbciao ^Cb^Cc04^C_Alice^C_^Cc !
----

=== Buffer e finestre

Un _buffer_ è composto da un numero, un nome, delle righe visualizzate (e
altri dati).

Esempi di buffer:

* buffer core (creato by WeeChat all'avvio, non può essere chiuso)
* server irc (mostra i messaggi dal server)
* canale irc
* query irc

// TRANSLATION MISSING
Una _finestra_ (o window) è un'area dello schermo in cui viene visualizzato
un buffer. È possibile dividere lo schermo in più finestre (examples
<<window_split_examples,below>>, see the <<command_weechat_window,/window>>
command for details).

Ogni finestra visualizza un buffer. Un buffer può essere nascosto (non visualizzato
da una finestra) o visualizzato da una o più finestre.

// TRANSLATION MISSING
Screen layouts and the association between windows and buffers can be
<<command_weechat_layout,saved and restored>>.

[[bare_display]]
==== Bare display

A special display, called "bare display" can be used for easy click on long URLs
and selection of text (using the mouse).

The bare display has following features:

* it displays only the content of current buffer: no window split neither bars
  (no title, nicklist, status, input, ...)
* the WeeChat mouse support is disabled (if it was enabled): you can use your
  mouse like you do in the terminal to click on URLs and select text
* ncurses is not used, therefore URLs are not cut at the end of lines.

The default key to enable bare display is kbd:[Alt+l] (`L`), and same key to exit
(or by default anything changing the input will exit the bare display, see option
<<option_weechat.look.bare_display_exit_on_input,weechat.look.bare_display_exit_on_input>>).

The time format can be customized with the option
<<option_weechat.look.bare_display_time_format,weechat.look.bare_display_time_format>>.

The bare display can be enabled for a specific delay using the command
<<command_weechat_window,/window>>.

[[buffers]]
=== Buffers

[[lines_format]]
==== Format of lines

Lines displayed in formatted buffers have following fields:

[width="100%",cols="2,2,10",options="header"]
|===
| Field               | Displayed          | Description
| date/time (message) | Yes                | Date/time of message (may be past).
| date/time (print)   | No                 | Date/time when WeeChat prints the message.
| prefix              | Yes                | Prefix of message, commonly a nick.
| message             | Yes                | The message itself.
| displayed           | No                 | Boolean: true if line is displayed, false if line is filtered with command <<command_weechat_filter,/filter>>.
| highlight           | No                 | Boolean: true if line has a highlight, false otherwise.
| tags                | With `/debug tags` | Tags associated with the line (see <<lines_tags,lines tags>>).
|===

The display of lines can be customized with many look options
(_pass:[weechat.look.*]_) and color options (_pass:[weechat.color.chat_*]_).

[[lines_tags]]
==== Lines tags

WeeChat uses tags in lines for different purposes:

* highlight
* notify level
* logging
* use of command <<command_weechat_filter,/filter>>

Tags can be displayed with the command `/debug tags` (same command to hide them).

Tag usati di frequente (elenco non esaustivo):

[width="100%",cols="1m,4",options="header"]
|===
| Tag              | Descrizione
| no_filter        | La riga non può essere filtrata.
| no_highlight     | Evidenziazione non possibile sulla riga.
| no_log           | La riga non viene scritta nel file di log.
// TRANSLATION MISSING
| log0 … log9      | Livello di log per la riga (see the <<command_logger_logger,/logger>> command).
// TRANSLATION MISSING
| notify_none      | The line must not be added to hotlist. ^(1)^
// TRANSLATION MISSING
| notify_message   | The line is a user message. ^(1)^
// TRANSLATION MISSING
| notify_private   | The line is a private message. ^(1)^
// TRANSLATION MISSING
| notify_highlight | The line is a message with highlight. ^(1)^
// TRANSLATION MISSING
| self_msg         | Self message.
| nick_xxx         | Il messaggio viene dal nick "xxx".
| prefix_nick_ccc  | Il prefisso è un nick con il colore "ccc".
// TRANSLATION MISSING
| host_xxx         | Username and host in message.
| irc_xxx          | Messaggio IRC "xxx" (può essere un comando o un numero di 3 cifre).
| irc_numeric      | Messaggio IRC numerico.
| irc_error        | Errore dal server IRC.
| irc_action       | Azione da un nic (comando `/me`).

| irc_smart_filter | Messaggio IRC filtrabile tramite lo "smart filter" (filtro intelligente).
| away_info        | Messagio con informazioni sull'assenza.
|===

// TRANSLATION MISSING
[NOTE]
^(1)^ When no tag "notify_xxx" is present, the default level is "low". If a tag
"notify_xxx" is present, the real notify level can be different, for example
if a max hotlist level is used for a nick, the notify level can be lower than
the value in the tag.

// TRANSLATION MISSING
[[local_variables]]
==== Local variables

Local variables can be defined in all buffers.

A local variable has:

* a name (string)
* a value (string, can be empty).

Local variables can be set by WeeChat, plugins, scripts, or manually on the
command line in the buffer.

For example to add the local variable "completion_default_template":

----
/buffer setvar completion_default_template %(my_completion)
----

To list local variables in the current buffer:

----
/buffer listvar
----

To remove the local variable "completion_default_template":

----
/buffer delvar completion_default_template
----

By default WeeChat and its default plugins interpret these variables:

[width="100%",cols="2m,2,5",options="header"]

[[buflist]]
=== List of buffers

// TRANSLATION MISSING
Buflist plugin displays a list of buffers in a bar item called "buflist"
(four other bar items "buflist2", "buflist3", "buflist4" and "buflist5" are
available as well). +
A default bar "buflist" is created on startup with this item.

[[cursor_mode]]
=== Cursor mode

The cursor mode allows you to move freely the cursor anywhere on screen, in chat
area and bars, and lets you perform actions at the given position. +
You can enter in cursor mode either with the command `/cursor` or with a mouse
middle click (mouse must have been enabled with key kbd:[Alt+m] or command
`/mouse enable`).

Typical use is to quote messages (chat area) or interact with nicks (nicklist bar).

See command <<command_weechat_cursor,/cursor>> and
<<key_bindings_cursor_context,key bindings in cursor context>> for the list
of actions you can perform in this mode.

[[colors_basic]]
==== Colori base

I colori base in WeeChat sono:

[width="75%",cols="1m,4",options="header"]
|===
| Nome         | Colore
| default      | Colore predefinito del terminale (trasparente per lo sfondo)
| black        | Nero
| darkgray     | Grigio scuro
| red          | Rosso scuro
| lightred     | Rosso chiaro
| green        | Verde scuro
| lightgreen   | Verde chiaro
| brown        | Marrone
| yellow       | Giallo
| blue         | Blu scuro
| lightblue    | Blu chiaro
| magenta      | Rosa scuro
| lightmagenta | Rosa chiaro
| cyan         | Azzurro scuro
| lightcyan    | Azzurro chiaro
| gray         | Grigio
| white        | Bianco
|===

[[colors_extended]]
==== Colori estesi

WeeChat alloca dinamicamente le coppie colore quando vengono usati i colori
sullo schermo (per mostrare buffer e barre).

In aggiunta ai colori di base, si può usare un numero per il colore compreso
tra 1 e il limite del proprio terminale.

Il comando `/color` mostra i colori attivi ed i limiti. Com kbd:[Alt+c] si può
passare temporaneamente ai colori del terminale per sceglierne uno.

Se ad esempio si desidera visualizzare l'ora in arancione nel buffer:

----
/set weechat.color.chat_time 214
----

O se si desidera uno sfondo verde scuro per la barra di stato:

----
/set weechat.bar.status.color_bg 22
----

[[colors_aliases]]
==== Alias

Si possono aggiungere degli alias ai colori con il comando `/color alias` e
usarli in ogni opzione relativa al colore.

Ad esempio:

----
/color alias 214 orange
/set weechat.color.chat_delimiters orange
----

[[colors_attributes]]
==== Attributi

Esistono alcuni attributi per i colori. Uno o più attributi vanno aggiunti prima
del nome o del numero del colore:

// TRANSLATION MISSING
* `+%+`: blink
// TRANSLATION MISSING
* `+.+`: "dim" (half bright)
* `+*+` : testo in grassetto
* `+!+` : video inverso
* `+/+` : testo in corsivo
* `+_+` : testo sottolineato
// TRANSLATION MISSING
* `+|+`: keep attributes: do not reset blink/dim/bold/reverse/italic/underlined
  when changing color

Ad esempio se si vuole il proprio nick bianco e sottolineato:

----
/set weechat.color.chat_nick_self _white
----

O se si desidera l'ora nella barra di stato arancione sottolineata
e in grassetto:

----
/set weechat.color.status_time *_214
----

Per usare un attributo con il colore predefinito del terminale (-1), bisogna
usare un numero maggiore dell'ultimo colore del terminale, ad esempio il
numero massimo in WeeChat: 99999.

Esempio di grassetto con il colore di primo piano del terminale:

----
/set weechat.color.status_time *99999
----

// TRANSLATION MISSING
[[themes]]
=== Themes

A theme is a named bundle of option overrides that can be applied with
the <<command_weechat_theme,/theme>> command. WeeChat ships a built-in
`"light"` theme tuned for light-background terminals and supports
user-defined themes loaded transiently from files.

[[themes_themable_options]]
==== Themable options

Themes can only set options marked as _themable_. All `*.color.*`
options are themable by default; a few string options that hold format
expressions with `+${color:...}+` references (such as
`+weechat.color.chat_nick_colors+`, `+weechat.look.prefix_error+` or the
`+buflist.format.*+` formats) are explicitly opted in.

You can list the full themable surface area from the
<<command_fset_fset,/fset>> buffer with the `+t:themable+` filter.

[[themes_apply]]
==== Applying a theme

To switch to the built-in light-background theme:

----
/theme apply light
----

The current state of every themable option is saved beforehand to a
backup theme file named like `+backup-YYYYMMDD-HHMMSS-uuuuuu+` in
directory `+themes+` inside the WeeChat configuration directory, so the
previous look can be restored at any time with:

----
/theme apply backup-YYYYMMDD-HHMMSS-uuuuuu
----

Backup creation can be disabled (not recommended):

----
/set weechat.look.theme_backup off
----

If backup is enabled and the backup file cannot be written, the apply
is aborted before any option is changed.

The name of the last applied theme is stored in
`+weechat.look.theme+` (informational only; not re-applied at startup).

[[themes_reset]]
==== Resetting to defaults

To restore the look shipped with WeeChat, reset every themable option
to its default value:

----
/theme reset
----

A backup is written first (same gate as `+/theme apply+`); on backup
failure the reset is aborted before any option is changed.
`+weechat.look.theme+` is cleared too.

[[themes_save_delete]]
==== Saving and deleting user themes

Save the current themable options as a new user theme file:

----
/theme save mytheme
----

Every themable option is written, so the file is self-contained and
applies the exact same look on any WeeChat, regardless of its current
configuration.

Reserved names (built-in theme names like `+light+` and any name
starting with `+backup-+`) are refused. Files live at
`+${weechat_config_dir}/themes/<name>.theme+`.

Rename a user theme (typical use: keep a useful automatic backup
under a meaningful name):

----
/theme rename backup-20260525-094210-123456 mybackup
----

Built-in themes have no file and cannot be renamed; the target name
cannot match a built-in name or start with `+backup-+`, and the
target file must not already exist. The `+[info]+` `+name+` field
inside the file is rewritten so `/theme info` reports the new name
consistently.

Delete a user theme:

----
/theme del mytheme
----

This removes the file on disk; built-in themes cannot be deleted.

[[themes_file_format]]
==== Theme file format

A theme file is INI-like with two sections:

----
[info]
name = "solarized_light"
description = "Light-background theme inspired by Solarized"
date = "2026-05-25 09:42:10"
weechat = "4.10.0-dev"

[options]
weechat.color.chat = "darkgray"
weechat.color.separator = "blue"
irc.color.input_nick = "magenta"
buflist.format.number = "${color:28}${number}${if:${number_displayed}?.: }"
----

`+[info]+` is informational metadata shown by `/theme info`. `+[options]+`
holds the actual overrides; keys are the full option names that would
appear in `/set`. String values can be enclosed in double or single
quotes; quotes are stripped at parse time. Non-themable options listed
in a theme file are refused at apply time and logged to the core
buffer (so a `.theme` file imported from an untrusted source cannot
overwrite passwords, autoload lists, or startup commands).

User theme files are never cached: on every `/theme apply <name>` the
file is parsed, applied, and freed.

[[themes_resolution]]
==== Resolution order

When `+/theme apply <name>+` is run:

* If `+${weechat_config_dir}/themes/<name>.theme+` exists, the file
  is parsed and used (it shadows any built-in with the same name).
* Otherwise the built-in theme registry is consulted; built-ins are
  registered programmatically by core, plugins and scripts (see the
  plugin and scripting documentation for `+weechat_theme_register+`).

If neither source provides the name, the apply is refused.

[[charset]]
=== Charset

Il plugin Charset consente di decodificare o codificare dati utilizzando
i set caratteri.

Esiste un set caratteri predefinito per la codifica/decodifica, e set caratteri
specifici per i buffer (o gruppi di buffer).

Questo plugin è opzionale, ma raccomandato: se non caricato, WeeChat
può leggere/scrivere soltanto dati UTF-8.

Il plugin Charset dovrebbe essere caricato automaticamente da WeeChat.
Per essere sicuri che sia caricato, provare con:

----
/charset
----

Se non trovato, allora si deve caricare il plugin con il comando:

----
/plugin load charset
----

Se il plugin non viene trovato, allora è necessario ricompilare WeeChat
con il supporto ai plugin e a Charset.

Quando viene avviato il plugin Charset, mostra i set caratteri del
terminale e quello interno. Il set caratteri dipende dal proprio
locale, mentre quello interno è UTF-8.

Per esempio:

....
set caratteri: terminale: ISO-8859-15, interno: UTF-8
....

[[charset_set]]
==== Impostare il set caratteri

Per impostare il set caratteri globale per la codifica e la decodifica,
utilizzare il comando `/set`.

Per esempio:

----
/set charset.default.decode ISO-8859-15
/set charset.default.encode ISO-8859-15
----

Se il set caratteri globale per la decodifica non è impostato (ad
esempio durante il primo caricamento del plugin Charset), verrà
impostato automaticamente sul set caratteri del terminale (se
diverso da UTF-8), oppure su _ISO-8859-1_.

Il valore di codifica predefinito è vuoto, perciò il testo viene
inviato per default con il set caratteri interno (UTF-8).

Per impostare il set caratteri del server IRC, utilizzare il comando `charset`
sul buffer del server. Se viene immesso solo il set caratteri, allora i valori
di codifica e decodifica saranno gli stessi.

Ad esempio:

----
/charset ISO-8859-15
----

È l'equivalente di:

----
/charset decode ISO-8859-15
/charset encode ISO-8859-15
----

Per impostare il set caratteri per il canale IRC (o il privato), utilizzare gli
stessi comandi per il server, ma sul buffer del canale (o quello privato).

// TRANSLATION MISSING
To set charset for all channels/privates of an IRC server:

----
/set charset.encode.irc.libera ISO-8859-15
----

Per visualizzare tutti i set caratteri utilizzati, utilizzare il comando seguente:

----
/set charset.*
----

[[notify_levels]]
=== Livelli di notifica

// TRANSLATION MISSING
[[setup_notify_levels]]
==== Setup notify levels

Sono possibili quattro livelli per i messaggi mostrati nei buffer, dal più basso
al più alto:

* _low_: messaggio di bassa importanza (ad esempio entrata/uscita/disconnessione
  di irc)
* _message_: messaggio da un utente
* _private_: messaggio in un buffer privato
* _highlight_: messaggio con notifica

Ogni buffer ha un livello di notifica, che viene usato per decidere quale
messaggio il buffer andrà ad aggiungere nella hotlist.

Il livello predefinito di notifica può essere impostato usando l'opzione
<<option_weechat.look.buffer_notify_default,weechat.look.buffer_notify_default>>,
il valore predefinito è _all_.

[width="75%",cols="2m,7",options="header"]
|===
| Livello di notifica | Livello del messaggio aggiunto alla hotlist
| none                | (nessuno)
| highlight           | highlight + private
| message             | highlight + private + message
| all                 | highlight + private + message + low
|===

Il livello di notifica può essere definito per un set di buffer, ad esempio
tutti i buffer per il server irc "libera":

----
/set weechat.notify.irc.libera message
----

Imposta il livello di notifica _highlight_ solo sul canale _#weechat_:

----
/set weechat.notify.irc.libera.#weechat highlight
----

Il livello di notifica per un buffer può essere impostato con il comando `/buffer`:

----
/buffer notify highlight
----

// TRANSLATION MISSING
[[max_hotlist_level_nicks]]
==== Max hotlist level for nicks

It is possible to set max hotlist level for some nicks, per buffer, or per group
of buffers (like IRC servers).

The buffer property "hotlist_max_level_nicks" can be set with a list of nicks
and for each nick the max hotlist level to trigger, possible levels are:

* -1: no hotlist changes for nick
* 0: low priority (like join/part messages)
* 1: message
* 2: private message
* 3: highlight (in fact useless, since it's already the default max for all messages)

For example to disable highlights from "joe" and "mike" on current buffer:

----
/buffer setauto hotlist_max_level_nicks_add joe:2,mike:2
----

// TRANSLATION MISSING
[[highlights]]
=== Highlights

// TRANSLATION MISSING
[[highlights_disable]]
==== Disable highlights

You can disable highlights with option
<<option_weechat.look.highlight_disable_regex,weechat.look.highlight_disable_regex>>
(regular expression). +
When a highlight is disabled with this option, the other highlight options are
ignored.

For example to disable any highlight on messages with a word beginning
with "flash" between chevrons:

----
/set weechat.look.highlight_disable_regex "<flash.*>"
----

This can also be set with the buffer property "highlight_disable_regex".

Same example, specific to the current buffer:

----
/buffer setauto highlight_disable_regex <flash.*>
----

[[highlights_words]]
==== Add words to highlight

By default, WeeChat highlights messages from other users containing your nick,
therefore the highlight depends on the buffer (the nick can be different from
one buffer to another).

You can add other words to highlight with the option
<<option_weechat.look.highlight,weechat.look.highlight>>, for example to
highlight your nick and "word1", "word2" and all words beginning with "test":

----
/set weechat.look.highlight "word1,word2,test*"
----

If you need a more specific rule for the word, you can use regular expressions
with the option <<option_weechat.look.highlight_regex,weechat.look.highlight_regex>>,
for example to highlight words "flashcode", "flashcöde" and "flashy":

----
/set weechat.look.highlight_regex "flashc[oö]de|flashy"
----

The delimiters around words to highlight can be customized with the option
<<option_weechat.look.word_chars_highlight,weechat.look.word_chars_highlight>>.

[[highlights_tags]]
==== Add tags to highlight

Lines displayed can contain "tags", which give some info about the origin of
message or the message itself. +
You can display tags with the command `/debug tags` (same command to hide them).

You can add specific tags to highlight with the option
<<option_weechat.look.highlight_tags,weechat.look.highlight_tags>>.
Tags are separated by commas, and multiple tags can be separated by `+++` to do
a logical "and" between them.

For example to highlight all messages from nick "FlashCode" and all notices
from nicks beginning with "toto":

----
/set weechat.look.highlight_tags "nick_flashcode,irc_notice+nick_toto*"
----

[[highlights_regex_buffer]]
==== Set extra highlights on buffer

You can force highlight using a regular expression with the buffer property
"highlight_regex".

For example to force the highlight on all messages in the current buffer:

----
/buffer setauto highlight_regex .*
----

// TRANSLATION MISSING
[[buffer_logging]]
=== Buffer logging

Il plugin Logger consente di salvare il contenuto dei buffer su file, con
opzioni a proposito su cosa e come viene salvato.

[[logger_log_levels]]
==== Livelli di log

Il logging viene effettuato con un livello per ogni buffer. Il livello
predefinito è il 9 (registra tutti i messaggi visualizzati sul buffer).
È possibile cambiare il livello per un buffer, oppure per un gruppo di buffer.

I livelli possibili sono da 0 a 9. Zero vuol dire "non registrare nulla" mentre
9 "registra tutto".

I plugin utilizzano livelli diversi per i messaggi visualizzati.
Il plugin IRC usa i seguenti livelli:

* livello 1: messaggio da un utente (su canale o privato)
* livello 2: cambio nick (proprio o di qualcun altro)
* livello 3: ogni messaggio del server (esclui entrata/uscita/disconnessione)
* livello 4: messaggio del server entrata/uscita/disconnessione

Se viene impostato il livello 3 per un canale IRC, WeeChat registrerà
tutti i messaggi, ma non quelli di entrata/uscita/disconnessione.

Alcuni esempi:

* imposta il livello 3 per il canale IRC #weechat:

----
/set logger.level.irc.libera.#weechat 3
----

* set level 3 for libera server buffer:

----
/set logger.level.irc.server.libera 3
----

* imposta il livello 3 per tutti i canali sul server libera:

----
/set logger.level.irc.libera 3
----

* imposta il livello 2 per tutti i buffer IRC:

----
/set logger.level.irc 2
----

[[logger_filenames_masks]]
==== Mask per il nome file

// TRANSLATION MISSING
È possibile definire un mask per il nome del file di ogni buffer, ed utilizzare
le variabili buffer locali per costruire il nome del file. To see available
local variables for current buffer:

----
/buffer listvar
----

// TRANSLATION MISSING
Masks will be matched on options in descending order of specificity on
`logger.mask.$plugin.*`, with `logger.file.mask` as fallback option.

Ad esempio, sul buffer "irc.libera.#weechat", WeeChat cercherà un mask con il
nome dell'opzione, in quest'ordine:

----
logger.mask.irc.libera.#weechat
logger.mask.irc.libera
logger.mask.irc
logger.file.mask
----

Ciò vuol dire che si hanno dei mask specifici per alcuni server
IRC ("logger.mask.irc.libera") o per un plugin ("logger.mask.irc").

[[logger_files_by_date]]
===== File di log per data

Per avere file di log per data, è possibile usare specificatori data/ora
nei mask (consultare `man stfrtime` per i formati), ad esempio:

----
/set logger.file.mask "%Y/%m/$plugin.$name.weechatlog"
----

Si avranno i seguenti file:

....
~/.local/share/weechat

[[logger_irc_files_by_server_channel]]
===== File di log IRC per server e canale

[[logger_rotation_compression]]
==== Rotation and compression

It is possible to define a max size for log files, and when it is reached,
there is automatic rotation of log file.

The rotated log files can be compressed with gzip or
https://facebook.github.io/zstd/[zstd ^↗^^].

[NOTE]
As the compression of a file can take some time, it is performed in background.

Example with a max size of 2GB and compression with gzip, using good compression
level (slower than default one):

----
/set logger.file.rotation_compression_type gzip
/set logger.file.rotation_compression_level 80
/set logger.file.rotation_size_max "2g"
----

If you want to use a decimal number, you can use the unit below and multiply
by 1000, for example to set max size to 2.5GB:

----
/set logger.file.rotation_size_max "2500m"
----

With these settings, you'll end with files like these ones (in this example
there is rotation only for the log of #weechat channel):

....
~/.local/share/weechat
└── logs
    ├── core.weechat.weechatlog
    ├── irc.server.libera.weechatlog

[[mouse]]
=== Supporto del mouse

WeeChat supporta i click e le azioni del mouse. Funziona con il terminale
locale, e da remoto via connessione ssh con o senza screen/tmux.

[[mouse_enable]]
==== Abilitare il mouse

Per abilitare il mouse all'avvio:

----
/set weechat.look.mouse on
----

Per abilitarlo subito, digitare kbd:[Alt+m] oppure eseguire il seguente comando:

----
/mouse enable
----

È possibile disabilitarlo temporaneamente, e associare il comando ad un
tasto. Ad esempio il tasto kbd:[Alt+%] per disabilitare il mouse per 10 secondi:

----
/key bind meta-% /mouse toggle 10
----

// TRANSLATION MISSING
[IMPORTANT]
When mouse is enabled in WeeChat, all mouse events are caught by WeeChat, so
actions such as copy/paste or clicks on URLs are not sent to the terminal. +
Using kbd:[Shift] key causes the events to be sent directly to the terminal,
as if the mouse was disabled (on some terminals like iTerm, you have to use
kbd:[Alt] instead of kbd:[Shift]).

[NOTE]
Per qualunque problema con il mouse, consultare
link:weechat_faq.it.html#mouse[FAQ di WeeChat / Mouse ^↗^^].

[[mouse_bind_events]]
==== Associare gli eventi del mouse a comandi

// TRANSLATION MISSING
Molti eventi del mouse predefiniti sono già definiti da WeeChat (consultare
<<key_bindings_mouse,mouse actions>>).

È possibile cambiare o aggiungere combinazioni con il comando `/key` usando il
contesto "mouse" (per la sintassi, consultare comando
<<command_weechat_key,/key>>).

Il nome dell'evento consiste di un modificatore (opzionale), il nome di un
pulsante/rotellina e un'azione (opzionale). Elementi diversi sono separati da `+-+`.

// TRANSLATION MISSING
List of modifiers (by order in the event name):

| ctrl         | Tasto kbd:[Ctrl]
| shift        | Tasto kbd:[Shift] ^(1)^
|===

// TRANSLATION MISSING
[NOTE]
^(1)^ The `shift` modifier can rarely be used in WeeChat because many terminals
use this modifier to catch directly mouse events.

// TRANSLATION MISSING
Several modifiers can be combined, for example:

* `alt-ctrl`
* `ctrl-shift`
* `alt-ctrl-shift`

* `button1-event-down`
* `button1-event-drag`
* `alt-button2-gesture-down-long`
* `wheelup`
* `alt-ctrl-wheeldown`
* ...

[TIP]
Quando si associa un tasto nel contesto "mouse", è possibile far corrispondere
più eventi usando `+*+` all'inizio o alla fine del nome, ad esempio
`+button1-gesture-*+` corrisponderà ad ogni azione compiuta col tasto sinistro.

[TIP]
È possibile trovare il nome di un evento con il comando `+/input grab_mouse+`
poi eseguire l'evento col mouse. Il comando inserisce il nome dell'evento
nella riga di comando.

[[spell_checking]]
=== Spell checking

Il plugin Spell consente di verificare l'ortografia nella riga di comando.
È possibile utilizzare più lingue per buffer.

// TRANSLATION MISSING
Spell checking is disabled by default and can be toggled with key kbd:[Alt+s].

// TRANSLATION MISSING
[[spell_dictionaries]]
==== Dictionaries

Before using spell checking, dictionaries must be defined, either globally or
specific to buffers.

Multiple dictionaries can be used at same time: WeeChat will check words in all
dictionaries.

For example to use English and French:

----
/set spell.check.default_dict "en,fr"
----

It is possible to use a different dictionary on a specific buffer, for example
on a German channel:

----
/spell setdict de
----

// TRANSLATION MISSING
You can also specify a dictionary for a group of buffers, for example English
for all channels on libera IRC server:

----
/set spell.dict.irc.libera en
----

For more information, see the command <<command_spell_spell,/spell>>.

[[spell_speller_options]]
==== Opzioni ortografiche

Le opzioni ortografiche possono essere definite aggiungendo opzioni nella
sezione "opzioni" della configurazione di aspell.

Il nome dell'opzione è un parametro di configurazione per aspell. L'elenco
delle opzioni disponibili può essere trovato nel terminale col seguente comando:

[source,shell]
----
aspell config
----

Ad esempio, per abilitare l'opzione "ignore-case":

----
/set spell.option.ignore-case "true"
----

// TRANSLATION MISSING
[[spell_suggestions]]
==== Suggestions

Suggestions are displayed in a bar item called "spell_suggest". The number of
suggestions is set in option _spell.check.suggestions_.

To enable suggestions you must set option _spell.check.suggestions_ to an
integer ≥ 0 and add the bar item "spell_suggest" to a bar, like _status_.

Example of suggestions with English dictionary (`en`):

[[bars]]
=== Bars

A _bar_ is an area beside the chat that can contain any type of text.

The bar options can be set with options `weechat.bar.name.option` where `name`
is the name of the bar and `option` the option for this bar.

List of bar options:

[width="100%",cols="2m,2,10",options="header"]
|===
| Option | Values | Description

| type | `root`, `window` |
// TRANSLATION MISSING
  A bar with type `root` is displayed exactly one time on screen, outside all
  windows. The default bar _buflist_ has type `root`. +
  A bar with type `window` is displayed in each window, for example if you
  split one time the screen (with `/window splith` or `/window splitv`), you
  will have one bar in each window. The default bars _title_, _status_,
  _input_ and _nicklist_ have type `window`.

| position | `top`, `bottom`, `left`, `right`
| Position of the bar: above/below chat, on the left/right.

| priority | integer ≥ 0
| Priority for display of bar: this is used for ordering the bars on screen when
  many bars have same type and position. +
  The bars are displayed from the edge of the screen to the center. A higher
  priority will display bar at the beginning, so closer to the edge. +
  Example: _input_ bar has priority 1000, so it is displayed before the _status_
  bar, which has priority 500.

| size | integer ≥ 0
| The size of the bar: number of columns for position left/right, number
  of lines for position top/bottom. A size of `0` means automatic, so the size
  will be computed according to content displayed in bar.

| size_max | integer ≥ 0
| The maximum size for a bar, `0` = no limit (this option is used only if
  `size` = `0`).

| color_bg | color
| The default background color for the bar.

| color_fg | color
| The default text color for the bar.

| color_delim | color
| The color for delimiters in bar.

| hidden | `on`, `off`
| When option is `on`, the bar is hidden. +
  Note: instead of changing this option, the command `/bar` is preferred, for
  example: `/bar toggle nicklist` (see command <<command_weechat_bar,/bar>>).

| separator | `on`, `off`
| When option is `on`, a separator (line) is displayed between this bar and
  other bars (or chat).

[[bar_items]]
==== Items

The option _items_ is a string with a list of bar items, separated by a comma
(space between items on screen) or `+++` (glued items).

The list of bar items is displayed with command `/bar listitems`.

// TRANSLATION MISSING
Before or after item name, you can use chars (that are not alphanumeric, `+-+`
or `+_+`). They will be displayed before/after item with the delimiters color
defined in bar (option _color_delim_).

Example of bar with items
"[time],buffer_number+:+buffer_plugin+.+buffer_name,[buffer_last_number]":

....
┌───────────────────────────────────────────────────────────────────────────┐
│[12:55] 3:irc/libera.#weechat [9]                                          │
└───────────────────────────────────────────────────────────────────────────┘
....

// TRANSLATION MISSING
[[item_spacer]]
===== Spacer item

An item called `spacer` can be used to align items (left, center, right).

When at least one `spacer` item is used in a bar, the whole bar width is used:
the spacers auto expand with the same size (or almost). +
When the bar is not large enough for all items, spacers are not displayed.

[NOTE]
The `spacer` bar item can be used only in bars with position `top` or `bottom`,
filling `horizontal` and size `1`.

Example of bar with items
"[time],spacer,buffer_number+:+buffer_plugin+.+buffer_name,spacer,[buffer_last_number]":

// TRANSLATION MISSING
[[item_force_buffer]]
===== Force buffer

// TRANSLATION MISSING
A special syntax can be used to force the buffer used when displaying the bar
item: "@buffer:item" (where "buffer" is the full name of buffer and "item" is
the name of a bar item).

// TRANSLATION MISSING
This is useful in root bars, to display item for a specific buffer which is
not displayed in the current window (or even not displayed at all).

// TRANSLATION MISSING
Example: nicklist of bitlbee in a root bar (if the bar is called
_bitlist_ and if bitlbee server is called _bitlbee_):

----
/set weechat.bar.bitlist.items "@irc.bitlbee.&bitlbee:buffer_nicklist"
----

// TRANSLATION MISSING
[[custom_bar_items]]
===== Custom bar items

Custom bar items can be added with the <<command_weechat_item,/item>> command,
each new item having two properties defined via configuration options:

* `conditions`: evaluated conditions to display the bar item, for example to
  restrict the bar item to some specific buffers (if empty, the bar item is
  displayed everywhere)
* `content`: evaluated content of bar item.

In both options, the following variables can be used:

* `window`: pointer to the window where the bar is displayed (`NULL` for root bars)
* `buffer`: pointer to buffer where the bar is displayed (current buffer for root bars).

Examples of conditions:

[width="100%",cols="3,10",options="header"]
|===
| Condition | Description
| `${window}` | Displayed in window bars only
| `${buffer.number} == 1` | Displayed in all buffers with number = 1
| `${buffer.plugin.name} == irc` | Displayed in all IRC buffers
| `${type} == channel` | Displayed in all buffers where local variable `type` is set to `channel` (example: all IRC channels)
| `${type} == private` | Displayed in all buffers where local variable `type` is set to `private` (example: all IRC private buffers)
|===

[NOTE]
There's no builtin way to refresh the custom bar items. You can use the
<<trigger,Trigger>> plugin to force the refresh, for example via one or more
signals received.

For more information and examples, see the <<command_weechat_item,/item>> command.

[[bar_filling]]
==== Filling

There are four types of filling:

* `+horizontal+`: the items are displayed horizontally, from left to right. If
  there are new lines in items, a space is used to separate lines.
* `+vertical+`: the items are displayed from top to bottom. If there are new
  lines in items, a new line is used to separate lines.
* `+columns_horizontal+`: items are displayed using columns, where text is
  aligned on the left. The first item is on top left, the second is on same
  line, on the right.
* `+columns_vertical+`: items are displayed using columns, where text is aligned
  on the left. The first item is on top left, the second is one line below.

Default bars _title_, _status_ and _input_ have _horizontal_ filling, and
default bar _nicklist_ has _vertical_ filling.

Some examples of filling for bar _nicklist_:

[[bar_conditions]]
==== Conditions

// TRANSLATION MISSING
The option _conditions_ is a string which is evaluated to know if the bar
must be displayed or not.

The string can be:

* _active_: the window must be active
* _inactive_: the window must be inactive
* _nicklist_: the buffer displayed in window must have a nicklist
* an expression: it is evaluated as boolean (see command
  <<command_weechat_eval,/eval>>)

For the expression, following variables are available:

* `+${active}+`: true if window is active
* `+${inactive}+`: true if window is inactive
* `+${nicklist}+`: true if buffer displayed in window has a nicklist

Following pointers are available:

* `+${window}+`: the window where condition is evaluated
* `+${buffer}+`: the buffer of window where condition is evaluated

Example to display nicklist bar in all buffers with a nicklist, and only if
width of terminal is > 100:

----
/set weechat.bar.nicklist.conditions "${nicklist} && ${info:term_width} > 100"
----

Same condition, but always display nicklist on buffer _&bitlbee_
(even if terminal is small):

----
/set weechat.bar.nicklist.conditions "${nicklist} && (${info:term_width} > 100 || ${buffer.full_name} == irc.bitlbee.&bitlbee)"
----

// TRANSLATION MISSING
[[secured_data]]
=== Secured data

[[secured_data_storage]]
==== Storage

WeeChat can encrypt passwords or private data using secured data, stored in file
_sec.conf_.

This configuration file is read before any other file, and the values stored
inside can be used in various WeeChat or plugins/scripts options.

You can set a passphrase to encrypt data in _sec.conf_. This is not mandatory
but highly recommended, otherwise data is stored as plain text in file.

----
/secure passphrase this is my passphrase
----

// TRANSLATION MISSING
[[secured_data_passphrase_on_startup]]
===== Passphrase on startup

When a passphrase is set, WeeChat will ask you to enter it on startup
(but not on `/upgrade`).

If you are using a password manager, you can run an external program to read
the passphrase instead of having to type it manually on WeeChat startup. +
For example with password-store (command `pass`):

----
/set sec.crypt.passphrase_command "/usr/bin/pass show weechat/passphrase"
----

The program may ask you unlock your GPG key or enter another passphrase to
read the secret. WeeChat will wait for the end of the command to read the
passphrase on the standard output (it must be on the first line without any
extra character). +
If the output contains no passphrase or if it is wrong, WeeChat will then ask
you to enter it.

[[secured_data_encryption]]
===== Encryption

The encryption of data is made in 3 steps:

. Derive a key from the passphrase (with optional salt).
. Compute hash of data to encrypt.
. Encrypt the hash + data (output is: salt + encrypted hash/data).

[NOTE]
The cipher block mode is _CFB_.

The result is put as hexadecimal string in file _sec.conf_, for example:

----
[data]
__passphrase__ = on
libera = "53B1C86FCDA28FC122A95B0456ABD79B5AB74654F21C3D099A6CCA8173239EEA59533A1D83011251F96778AC3F5166A394"
----

[[secured_data_decryption]]
===== Decryption

The decryption of data is made in 3 steps:

. Derive a key using salt and passphrase.
. Decrypt hash + data.
. Check that decrypted hash == hash of data.

[[secured_data_manage]]
==== Manage secured data

To add secured data, use `/secure set`, for example a password for _libera_
IRC server:

----
/secure set libera mypassword
----

For comfort, secured data can be displayed in a dedicated buffer (kbd:[Alt+v] on
buffer to see values), just do:

----
/secure
----

Secured data can be used in some options that can contain private data like
password, using this format: "${sec.data.xxx}" where "xxx" is the name of
secured data (used with `/secure set xxx ...`). +
For a complete list of supported options, see the <<command_weechat_secure,/secure>> command.

To use the _libera_ password, for example with
<<irc_sasl_authentication,SASL authentication>>:

----
/set irc.server.libera.sasl_password "${sec.data.libera}"
----

=== Command aliases

Il plugin Alias consente di creare alias per i comandi (da WeeChat o altri
plugin).

[[irc]]
== IRC

Il plugin IRC è realizzato per chattare tramite protocollo IRC con altre persone.

È multi-server, ed offre tutti i comandi IRC supportati inclusi la chat DCC ed il
trasferimento file (tramite plugin xfer, consultare <<xfer,plugin Xfer>>).

[[irc_command_line_options]]
=== Opzioni a riga di comando

È possibile fornire un URL per uno o più server IRC, come segue:

----
irc[6][s]://[nick[:password]@]irc.esempio.org[:porta][/#canale][,#canale[...]]
----

Esempio per entrare in _#weechat_ e _#weechat-fr_ sul server _irc.libera.chat_,
porta predefinita (6667), con il nick _alice_:

[source,shell]
----
weechat irc://alice@irc.libera.chat/#weechat,#weechat-fr

// TRANSLATION MISSING
[[irc_servers]]
=== Servers

[[irc_servers_add]]
==== Add a server

By default no servers are defined. You can add as many servers as you want with
the <<command_irc_server,/server>> command.

For example to connect to https://libera.chat/[libera.chat ^↗^^]:

----
/server add libera irc.libera.chat
----

[NOTE]
Default port is 6697 and TLS (encrypted traffic) is enabled.

You can tell WeeChat to auto-connect to this server on startup:

----
/set irc.server.libera.autoconnect on
----

To authenticate, it is recommended to use SASL (if supported on the server),
with the password stored as secured data (see also chapter on
<<irc_sasl_authentication,SASL authentication>>):

----
/set irc.server.libera.sasl_username "alice"
/secure set libera xxxxxxx
/set irc.server.libera.sasl_password "${sec.data.libera}"
----

If SASL is not supported, you can use a command to send a message to nickserv:

----
/set irc.server.libera.command "/msg nickserv identify ${sec.data.libera}"
----

[NOTE]
By sending a message to nickserv, you may authenticate after joining channels
which could be a problem on some channels requiring you to be authenticated
to join. In this case, you can set a command delay:
`/set irc.server.libera.command_delay 5`.

[[irc_servers_options]]
==== Server options

Server options are named `irc.server.<server>.<option>` where `<server>` is the
internal name of the server and `<option>` the name of an option. +
The value of a server option is inherited from `irc.server_default.xxx`
if the server option has the special value `null`.

For example if you created the _libera_ server with the commands above, you'll
see this with the command `/fset libera`:

....
irc.server.libera.addresses             stringa  "irc.libera.chat"
irc.server.libera.anti_flood            intero   null -> 2000
irc.server.libera.autoconnect           bool     on
irc.server.libera.autojoin              stringa  null -> ""

....

For example if you want to automatically connect to all servers you define
without having to do it on each server, you can do:

----
/set irc.server_default.autoconnect on
----

And then you can reset the server option so that it uses the default inherited
value, which is now `on` instead of the default value `off`:

----
/unset irc.server.libera.autoconnect
----

[[irc_tls_certificates]]
==== Certificati TLS

Al momento della connessione al server IRC con TLS, WeeChat verifica in
maniera predefinita che la connessione sia completamente fidata.

Esistono alcune opzioni per controllare la connessione TLS:

// TRANSLATION MISSING
weechat.network.gnutls_ca_system::
    load system's default trusted certificate authorities on startup

// TRANSLATION MISSING
weechat.network.gnutls_ca_user::
    extra file(s) with certificate authorities

irc.server.xxx.tls_cert::
    file del certificato TLS usato per identificare automaticamente il proprio
    nick ad esempio CertFP su oftc (a seguire)

irc.server.xxx.tls_dhkey_size::
    dimensione della chiave usata durante lo Scambio Chiavi Diffie-Hellman
    (predefinita; 2048)

irc.server.xxx.tls_verify::
    verifica che la connessione TLS sia totalmente fidata (opzione attivata
    in maniera predefinita)

[NOTE]
L'opzione "tls_verify" è attivata per default, in questo modo la verifica è rigorosa
e potrebbe fallire, anche se funziona senza problemi con versioni precedenti
la 0.3.1.

[[irc_connect_oftc_with_certificate]]
===== Primo esempio: connessione a otfc e verifica del certificato

* Importare certificati nella shell:

[source,shell]
----
mkdir -p ~/.config/weechat/tls
wget -O ~/.config/weechat/tls/CAs.pem https://www.spi-inc.org/ca/spi-cacert.crt
----

// TRANSLATION MISSING
[NOTE]
You must replace `~/.config/weechat` by the path to your WeeChat config directory
which can also be for example `~/.weechat`.

// TRANSLATION MISSING
[NOTE]
E possibile concatenare più certificati nel file CAs.pem.

// TRANSLATION MISSING
* In WeeChat, with "oftc" server already added:

----
/connect oftc
----

[[irc_connect_oftc_with_certfp]]
===== Secondo esempio: connessione a otfc con CertFP

* Creare un certificato nella shell:

[source,shell]
----
mkdir -p ~/.config/weechat/tls
cd ~/.config/weechat/tls
openssl req -nodes -newkey rsa:2048 -keyout nick.pem -x509 -days 365 -out nick.pem
----

// TRANSLATION MISSING
[NOTE]
You must replace `~/.config/weechat` by the path to your WeeChat config directory
which can also be for example `~/.weechat`.

// TRANSLATION MISSING
* In WeeChat, with "oftc" server already added:

----
/set irc.server.oftc.tls_cert "${weechat_config_dir}/tls/nick.pem"
/connect oftc
/msg nickserv cert add
----

// TRANSLATION MISSING

[[irc_sasl_authentication]]
==== Autenticazione SASL

// TRANSLATION MISSING
WeeChat supports SASL authentication, using different mechanisms:

// TRANSLATION MISSING
* _plain_: password in chiaro (default)
// TRANSLATION MISSING
* _scram-sha-1_: SCRAM with SHA-1 digest algorithm
// TRANSLATION MISSING
* _scram-sha-256_: SCRAM with SHA-256 digest algorithm
// TRANSLATION MISSING
* _scram-sha-512_: SCRAM with SHA-512 digest algorithm
// TRANSLATION MISSING
* _ecdsa-nist256p-challenge_: challenge with public/private key
* _external_: certificato TLS da lato client

Le opzioni nel server sono:

// TRANSLATION MISSING
* _sasl_mechanism_: meccanismo da usare (see above)
* _sasl_timeout_: timeout (in secondi) per l'autenticazione
// TRANSLATION MISSING
* _sasl_fail_: action to perform if authentication fails
* _sasl_username_: nome utente (nick)
* _sasl_password_: password
// TRANSLATION MISSING
* _sasl_key_: file with ECc private key (for mechanism
  _ecdsa-nist256p-challenge_)

// TRANSLATION MISSING
[[irc_sasl_ecdsa_nist256p_challenge]]
===== SASL ECDSA-NIST256P-CHALLENGE

You must generate a private key in order to authentify with the
ECDSA-NIST256P-CHALLENGE mechanism (no password is required on connection).

You can generate the key with this command:

[source,shell]
----
openssl ecparam -genkey -name prime256v1 -out ~/.config/weechat/ecdsa.pem
----

[NOTE]
You must replace `~/.config/weechat` by the path to your WeeChat config directory
which can also be for example `~/.weechat`.

Get the public key (encoded as base64) with this command:

[source,shell]
----
openssl ec -noout -text -conv_form compressed -in ~/.config/weechat/ecdsa.pem | grep '^pub:' -A 3 | tail -n 3 | tr -d ' \n:' | xxd -r -p | base64
----

Connect to the server, identify (for example with "nickserv identify") and set
your public key in your account, using nickserv (replace the base64 value with
your public key):

----
/connect libera
/msg nickserv identify your_password
/msg nickserv set pubkey Av8k1FOGetUDq7sPMBfufSIZ5c2I/QYWgiwHtNXkVe/q
----

Configure the SASL options in the server:

----
/set irc.server.libera.sasl_mechanism ecdsa-nist256p-challenge
/set irc.server.libera.sasl_username "your_nickname"
/set irc.server.libera.sasl_key "${weechat_config_dir}/ecdsa.pem"
----

Reconnect to the server:

----
/reconnect libera
----

// TRANSLATION MISSING
[[irc_servers_connection]]
==== Connection

You can connect to server with the <<command_irc_connect,/connect>> command:

----
/connect libera
----

To disconnect:

----
/disconnect libera
----

Or just this if you are on any buffer belonging to _libera_ server (server,
channel, private):

----
/disconnect
----

When you connect to multiple servers at same time, server buffers are merged
by default and you can switch between them with the kbd:[Ctrl+x] key. +
It is possible to disable auto merge of server buffers to have independent
server buffers:

----
/set irc.look.server_buffer independent
----

// TRANSLATION MISSING
[[irc_tor_sasl]]
==== Connect with Tor and SASL

// TRANSLATION MISSING
Some servers support connections with https://www.torproject.org/[Tor ^↗^^],
a network of virtual tunnels that allows people and groups to improve their
privacy and security on the Internet.

Il primo passo consiste nell'installare Tor. Per Debian (e derivate):

[source,shell]
----
sudo apt-get install tor
----

In WeeChat è necessario creare un proxy socks5 per il servizio Tor (nome
host/IP e porta dipendono dalla propria configurazione di Tor):

----
/proxy add tor socks5 127.0.0.1 9050
----

// TRANSLATION MISSING
Now, add a new server (replace server name "irc-tor" and the address by a valid one):

----
/server add irc-tor this.is.the.address.onion
----

Impostare il proxy per Tor:

----
/set irc.server.irc-tor.proxy "tor"
----

// TRANSLATION MISSING
Set SASL authentication with ECDSA-NIST256P-CHALLENGE (see the chapter
<<irc_sasl_ecdsa_nist256p_challenge,SASL ECDSA-NIST256P-CHALLENGE>> to generate
a private key):

----
/set irc.server.irc-tor.sasl_mechanism ecdsa-nist256p-challenge
/set irc.server.irc-tor.sasl_username "your_nickname"
/set irc.server.irc-tor.sasl_key "${weechat_config_dir}/ecdsa.pem"
----

// TRANSLATION MISSING
And finally, connect to the server:

----
/connect irc-tor
----

// TRANSLATION MISSING
[[irc_ircv3_support]]
=== IRCv3 support

WeeChat supports the following https://ircv3.net/irc/[IRCv3 extensions ^↗^^]:

* <<irc_ircv3_account_notify,account-notify>>
* <<irc_ircv3_account_tag,account-tag>>
* <<irc_ircv3_away_notify,away-notify>>

* <<irc_ircv3_typing,typing>>
* <<irc_ircv3_userhost_in_names,userhost-in-names>>
* <<irc_ircv3_whox,WHOX>>

By default all capabilities supported by the server and WeeChat are
automatically enabled
(see option <<option_irc.server_default.capabilities,irc.server_default.capabilities>>).

Tables with comparison of different IRC clients, including WeeChat, are available
on https://ircv3.net/software/clients[this page ^↗^^].

[[irc_ircv3_account_notify]]
==== account-notify

Specification: https://ircv3.net/specs/extensions/account-notify[account-notify ^↗^^]

This capability allows the server to send messages when users identify or
unidentify on the server. +
WeeChat displays such messages if the option
<<option_irc.look.display_account_message,irc.look.display_account_message>>
is enabled (default value).

Examples:

....
-- alice has identified as Alice01

-- alice has unidentified
....

[[irc_ircv3_account_tag]]
==== account-tag

Specification: https://ircv3.net/specs/extensions/account-tag[account-tag ^↗^^]

This capability allows the server to send account as message tag to commands
sent to the client. +
WeeChat parses this tag and saves it in the message, but it is not used or
displayed. It can be used in <<command_weechat_filter,/filter>> command to filter
messages matching specific accounts.

Example of raw IRC message received:

....
@account=Alice01 :user@example.com PRIVMSG #test :Hello!
....

Message displayed in channel:

....
<alice> Hello!
....

Message with tags:

....
<alice> Hello! [irc_privmsg,irc_tag_account_Alice01,notify_message,prefix_nick_lightcyan,nick_alice,host_user@example.com,log1]
....

[[irc_ircv3_away_notify]]
==== away-notify

Specification: https://ircv3.net/specs/extensions/away-notify[away-notify ^↗^^]

This capability allows the server to send away notifications for users present
on the same channels as you.

When the away status is changed for a user (away or back), this is reflected
with a specific color in the nicklist, using the following options:

* <<option_irc.server_default.away_check,irc.server_default.away_check>>
* <<option_irc.server_default.away_check_max_nicks,irc.server_default.away_check_max_nicks>>
* <<option_weechat.look.item_away_message,weechat.look.item_away_message>>

[[irc_ircv3_batch]]
==== batch

Specification: https://ircv3.net/specs/extensions/batch[batch ^↗^^]

This capability allows the server to send batched events (grouping of several
messages that are related).

For now, WeeChat only stores messages received in a batch and processes as usual
later, when the batch ends.

[[irc_ircv3_cap_notify]]
==== cap-notify

Specification: https://ircv3.net/specs/extensions/capability-negotiation#the-cap-new-subcommand[cap-notify ^↗^^]

This capability allows the server to advertise on new or removed capabilities
on the server (via `CAP NEW` and `CAP DEL` commands).

Examples:

....
-- irc: client capability, now available: sasl

-- irc: client capability, removed: sasl
....

[[irc_ircv3_chghost]]
==== chghost

Specification: https://ircv3.net/specs/extensions/chghost[chghost ^↗^^]

This capability allows the server to send messages when users change name or host. +
When the option <<option_irc.look.smart_filter_chghost,irc.look.smart_filter_chghost>>
is enabled (default value), the host changes are automatically hidden if the nick
has not spoken for several minutes. +
The color of the change host message is controlled by the option
<<option_irc.color.message_chghost,irc.color.message_chghost>>.

Example:

....
-- alice (user@example.com) has changed host to test.com
....

// TRANSLATION MISSING
[[irc_ircv3_draft_multiline]]
==== draft/multiline

Specification: https://ircv3.net/specs/extensions/multiline[multiline ^↗^^]

This capability allows the client and server to send messages with multiple lines,
using the <<irc_ircv3_batch,batch>> capability, that must be enabled as well.

There are limits in term of bytes or number of lines in a multiline message
that are given in the capability sent by the server, for example:

....
CAP alice LS * :draft/multiline=max-bytes=4096,max-lines=24
....

This sets a limit of 4096 bytes and 24 lines for a multiline batched content.

If the limits are not given by the server, the default in WeeChat are:

* max bytes: 4096
* max lines: 24

Only standard messages and those send by the <<command_irc_notice,/notice>>
command can be multiline. +
ACTION CTCP messages sent with command <<command_irc_me,/me>> are not affected
by this capability. That means multiline actions are sent as multiple actions.

[WARNING]
As the specification is a "draft", it may change and the multiline support can
possibly break at any time in WeeChat. +
The capability is automatically enabled if the server supports it and can be
disabled with this command:
`/set irc.server_default.capabilities "*,!draft/multiline"`. +
When the capability is disabled, a multiline message is sent as multiple messages,
as if they were sent sequentially to the server.

Example of IRC messages sent for a user message with two lines (`this is a test`
/ `on two lines`), send to channel #test:

....
BATCH +i8Je7M7gquddoyC9 draft/multiline #test
@batch=i8Je7M7gquddoyC9 PRIVMSG #test :this is a test
@batch=i8Je7M7gquddoyC9 PRIVMSG #test :on two lines
BATCH -i8Je7M7gquddoyC9
....

Display of the message sent in WeeChat:

....
19:01:45 alice | this is a test
               | on two lines
....

// TRANSLATION MISSING
[[irc_ircv3_echo_message]]
==== echo-message

Specification: https://ircv3.net/specs/extensions/echo-message[echo-message ^↗^^]

This capability forces the server to send PRIVMSG, NOTICE and TAGMSG messages
back to WeeChat.

WeeChat displays only the message received and not the message sent, so a delay
can be noticed between the send and the display. When the message is displayed,
it means it has been properly received by the server and propagated to other
clients connected to the server as well.

[[irc_ircv3_extended_join]]
==== extended-join

Specification: https://ircv3.net/specs/extensions/extended-join[extended-join ^↗^^]

This capability allows the server to send account and real name when users
join channels. +
WeeChat displays this additional information in join messages if the option
<<option_irc.look.display_extended_join,irc.look.display_extended_join>>
is enabled (default value).

Example:

....
--> john [John01] (John Doe) (~user@example.com) has joined #test
....

[[irc_ircv3_invite_notify]]
==== invite-notify

Specification: https://ircv3.net/specs/extensions/invite-notify[invite-notify ^↗^^]

This capability allows the server to send invite messages when users are
invited to channels.

Example:

....
-- alice ha invitato bob in #test
....

[[irc_ircv3_message_tags]]
==== message-tags

Specification: https://ircv3.net/specs/extensions/message-tags[message-tags ^↗^^]

This capability allows to add metadata in messages. +
These tags can be displayed using the command `/debug tags`.

It must be enabled to use <<typing_notifications,typing notifications>>.

[[irc_ircv3_monitor]]
==== monitor

Specification: https://ircv3.net/specs/extensions/monitor[monitor ^↗^^]

This capability allows the server to send notifications when clients become
online/offline. +
WeeChat automatically uses this extension if available when using the
<<command_irc_notify,/notify>> command.

[[irc_ircv3_multi_prefix]]
==== multi-prefix

Specification: https://ircv3.net/specs/extensions/multi-prefix[multi-prefix ^↗^^]

This capability allows the server to send all user modes at once in
<<command_irc_names,/names>> and <<command_irc_whois,/whois>> responses. +

////
Example: output of `/names`:

....
-- Nick #test: [@%+alice bob +carol]
....
////

[NOTE]
For now, WeeChat doesn't display all prefixes in the `/names` output, even if
they are received and properly saved internally.

Example: output of `/whois alice`:

....
-- [alice] @%+#test
....

[[irc_ircv3_sasl]]
==== SASL

Specification: https://ircv3.net/specs/extensions/sasl-3.2[SASL 3.2 ^↗^^]

See the dedicated chapter <<irc_sasl_authentication,SASL authentication>>.

[[irc_ircv3_server_time]]
==== server-time

Specification: https://ircv3.net/specs/extensions/server-time[server-time ^↗^^]

This capability allows the server to send time for messages as message tag. +
When the time is received in a message, WeeChat uses it to display the message
(it can then be displayed with a past date).

The <<relay_irc_proxy,IRC proxy>> in Relay plugin supports this capability,
so any IRC client of Relay should enable it to display the real message time
in the backlog sent upon connection.

[[irc_ircv3_setname]]
==== setname

Specification: https://ircv3.net/specs/extensions/setname[setname ^↗^^]

This capability lets you change your real name by using the
<<command_irc_setname,/setname>> command.

[[irc_ircv3_typing]]
==== typing

Specification: https://ircv3.net/specs/client-tags/typing[typing ^↗^^]

See the dedicated chapter <<typing_notifications,Typing notifications>>.

[[irc_ircv3_userhost_in_names]]
==== userhost-in-names

Specification: https://ircv3.net/specs/extensions/userhost-in-names[userhost-in-names ^↗^^]

This capability allows the server to send hostnames in <<command_irc_names,/names>>
responses.

[NOTE]
WeeChat doesn't display hostnames in the `/names` output.

Example of raw IRC messages received without the capability:

....
:irc.server 353 alice = #test :@alice bob +carol
....

Example of raw IRC messages received with the capability:

....
:irc.server 353 alice = #test :@alice!user1@host1 bob!user2@host2 +carol!user3@host3
....

[[irc_ircv3_whox]]
==== WHOX

Specification: https://ircv3.net/specs/extensions/whox[WHOX ^↗^^]

This capability lets you request additional fields in the WHO response
(via the <<command_irc_who,/who>> command). +
WeeChat displays all additional information received in the WHO output.

// TRANSLATION MISSING
[[irc_channels]]
=== Channels

You can join channels with the <<command_irc_join,/join>> command:

----
/join #channel
----

Part a channel (keeping the buffer open):

----
/part [quit message]
----

The channels you joined are not saved. If you want to join them automatically
when connecting to the server, you must set the server `autojoin` option:

----
/set irc.server.libera.autojoin "#weechat,#weechat-fr"
----

[NOTE]
Some scripts can help to automatically set this option,
see `/script search autojoin`.

Be careful, spaces can be used only to separate list of channels from keys,
for example if `#channel1` requires a key but not `#channel2`:

----
/set irc.server.libera.autojoin "#channel1,#channel2 key1"
----

// TRANSLATION MISSING
For help on the format, see option <<option_irc.server_default.autojoin,irc.server_default.autojoin>>.

[[irc_private_messages]]
=== Private messages

You can send a private message with the <<command_irc_query,/query>> command,
which opens a separate buffer:

----
/query bob hi, how are you?
----

Without arguments the command just opens the buffer (or selects it if already open):

----
/query bob
----

To close the private buffer, you can do this command on the private buffer:

----
/close
----

// TRANSLATION MISSING
[[irc_smart_filter]]
=== Smart filter

A smart filter is available to filter some messages when someone did not write
anything in the channel during a configurable delay:

- join: user joins the channel
- part: user leaves the channel
- quit: user quits the server
- account: user changes its account
- chghost: user changes name or host
- mode: mode changes on channel
- nick: user changes its nick
- setname: user changes its real name

Smart filter is enabled by default, but you must add a filter to hide lines on
buffers, for example:

----
/filter add irc_smart * irc_smart_filter *
----

// TRANSLATION MISSING
It is possible to create filter for one channel only or channels beginning with
same name (see the <<command_weechat_filter,/filter>> command):

----
/filter add irc_smart_weechat irc.libera.#weechat* irc_smart_filter *
----

You can setup a longer delay (in minutes):

----
/set irc.look.smart_filter_delay 10
----

If someone did not write anything during last 10 minutes, its messages like
join/part/quit will be hidden by default on channel, and you can use key
kbd:[Alt+=] (toggle filters) to see them.

[[irc_ctcp_replies]]
=== Risposte CTCP

È possibile personalizzare le risposte CTCP, o bloccare alcune richieste CTCP
(non rispondere).

Ad esempio, per personalizzare la richiesta CTCP "VERSIONE", utilizzare il
seguente comando:

----
/set irc.ctcp.version "Uso WeeChat ${version}, fico!"
----

// TRANSLATION MISSING
[NOTE]
The name of CTCP must be in lower case. That means option _irc.ctcp.VERSION_
would not work.

Se si desidera bloccare CTCP "VERSIONE" (non rispondere ad una query),
allora basta impostare una stringa vuota:

----
/set irc.ctcp.version ""
----

Anche un CTCP sconosciuto può essere personalizzato, per esempio si
può rispondere "BLABLA":

----
/set irc.ctcp.blabla "Questa è la mia risposta a CTCP BLABLA"
----

È possibile personalizzare CTCP per un solo server, utilizzando il suo nome
interno prima del nome CTCP:

----
/set irc.ctcp.libera.version "WeeChat ${version} (per libera)"
----

Se si desidera ripristinare la risposta CTCP standard, allora disabilitare
l'opzione:

----
/unset irc.ctcp.version
----

// TRANSLATION MISSING
The CTCP replies are evaluated (see command <<command_weechat_eval,/eval>>) and
the following extra variables are available:

[width="100%",cols="2,4,8",options="header"]

[[irc_target_buffer]]
=== Buffer di destinazione per i messaggi IRC

È possibile personalizzare il buffer di destinazione per i messaggi IRC
(buffer usato per visualizzare messaggi) con l'opzione `+irc.msgbuffer.*+`.

Per alcuni messaggi IRC (elenco in basso), si possono usare i seguenti
valori:

current::
    buffer attivo (se è il buffer IRC, oppure sul buffer del server, come
    predefinito)

private::
    buffer privato per il nick, o il buffer corrente se non trovato
    (in base all'opzione _irc.look.msgbuffer_fallback_)

server::
    buffer del server

weechat::
    Il buffer "core" di WeeChat

Quando l'opzione non è impostata (default), WeeChat sceglie il buffer
appropriato, di solito quello del server o del canale.

Ecco una lista incompleta dei messaggi IRC o degli alias che è possibile
personalizzare:

Anche altri comandi numerici possono essere personalizzati.

Il messaggio può essere preceduto dal nome del server per essere più
precisi (ad esempio: `libera.whois`).

Alcuni esempi:

* visualizza il risultato di `/whois` su un buffer privato:

----
/set irc.msgbuffer.whois private
----

* ripristina il buffer predefinito per il whois (buffer del server):

----
/unset irc.msgbuffer.whois
----

* visualizza inviti sul buffer corrente, solo per il server "libera":

----
/set irc.msgbuffer.libera.invite current
----

* visualizza messaggio "303" (ison) sul buffer "core" di WeeChat:

----
/set irc.msgbuffer.303 weechat

[[typing_notifications]]
== Typing notifications

The typing plugin is used to inform other users you are typing messages and
show a list of users currently typing a message on the buffer.

It is used by IRC plugin on channel and private buffers, when the "message-tags"
capability is enabled (you can check with <<command_irc_cap,/cap>> command). +
Under the hood, typing client tag is used, following
https://ircv3.net/specs/client-tags/typing[this specification ^↗^^].

[[typing_activation]]
=== Activation

For privacy considerations, the typing feature is disabled by default. +
If you want to use it, you must enable options in both typing and irc plugins:

----
/set typing.look.enabled_nicks on
/set typing.look.enabled_self on
/set irc.look.typing_status_nicks on
/set irc.look.typing_status_self on
----

The typing notifications are displayed at the end of the status bar.

Example of status bar with the "typing" item: "bob" is typing a message and
"alice" was typing a message but made a pause:

....
│[12:55] [6] [irc/libera] 3:#test(+n){4} [Typing: bob, (alice)]                   │
│[@Flashy] █                                                                      │
└─────────────────────────────────────────────────────────────────────────────────┘
....

[[typing_signals_sent]]
=== Signals sent

When you are typing a message (not a command starting with `/`), the typing
plugin sends signals to inform other plugins (like IRC) that you are typing,
and these plugins can then send typing notifications to other users.

The following signals are sent when you are typing messages:

[width="100%",cols="1,1,5",options="header"]
|===
| Signal              | Arguments        | Description
| typing_self_typing  | Pointer: buffer. | You are typing a message.
| typing_self_paused  | Pointer: buffer. | You made a pause while typing a message.
| typing_self_cleared | Pointer: buffer. | You cleared the command line without sending the message.
| typing_self_sent    | Pointer: buffer. | You sent the message to the buffer.
|===

[[typing_signals_caught]]
=== Signals caught

The typing plugin is catching some signals that can be sent by other plugins
(like IRC), to update internal hashtables used to store the typing state of
nicks on buffers. These hashtables are used to build the content of "typing"
bar item.

The following signals are caught by the typing plugin:

[width="100%",cols="1,4,3",options="header"]
|===
| Signal | Arguments | Description

| typing_set_nick
| String: buffer pointer + ";" + state (one of: "off", "typing", "paused",
  "cleared") + ";" + nick. +
  Example: "0x1234abcd;typing;alice".
| Set typing state for a nick on a buffer.

| typing_reset_buffer
| Pointer: buffer.
| Remove typing state for all nicks on a buffer.

[[relay]]
== Relay

Il plugin Relay viene utilizzato per inoltrare i dati via rete, facendo uso di
protocolli differenti:

* _irc_: proxy IRC: usato per condividere le connessioni ai server IRC con uno
  o più client IRC
// TRANSLATION MISSING
* _api_: HTTP REST API, used by WeeChat and remote interfaces to display and
  interact with WeeChat
// TRANSLATION MISSING
* _weechat_: protocol used by remote interfaces to display and interact with
  WeeChat.

// TRANSLATION MISSING
For _api_ and _weechat_ protocols, see the list of remote interfaces on
https://weechat.org/about/interfaces/[this page ^↗^^].

// TRANSLATION MISSING
[[relay_password]]
=== Password

It is highly recommended to set a password for relay, with these commands:

----
/secure set relay miapass
/set relay.network.password "${sec.data.relay}"
----

// TRANSLATION MISSING
This password is used with all protocols.

// TRANSLATION MISSING
[[relay_totp]]
=== TOTP

// TRANSLATION MISSING
TOTP (Time-based One-Time Password) can be used as secondary authentication
factor for _api_ and _weechat_ protocols, in addition to the password.

This is optional and increases the security level.

One-time passwords can be generated with applications, for example:

* FreeOTP:
  https://play.google.com/store/apps/details?id=org.fedorahosted.freeotp[Android ^↗^^],
  https://apps.apple.com/fr/app/freeotp-authenticator/id872559395[iOS ^↗^^]
  (https://freeotp.github.io/[website ^↗^^])
* Google Authenticator:
  https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2[Android ^↗^^],
  https://apps.apple.com/fr/app/google-authenticator/id388497605[iOS ^↗^^]

The TOTP secret must be set in WeeChat and the application used to generate
one-time passwords.

It must be a string encoded in base32, with only letters and digits from 2 to 7,
for example:

----
/secure set relay_totp secretpasswordbase32
/set relay.network.totp_secret "${sec.data.relay_totp}"
----

[[relay_tls]]
=== TLS

È possibile usare TLS creando un certificato e una chiave privata, e usando il
prefisso "tls." nel nome del protocollo.

// TRANSLATION MISSING
The default path to certificate/key is defined by option
<<option_relay.network.tls_cert_key,relay.network.tls_cert_key>>.

È possibile creare un certificato e una chiave privata con i seguenti comandi:

[source,shell]
----
mkdir -p ~/.config/weechat/tls
cd ~/.config/weechat/tls
openssl req -nodes -newkey rsa:2048 -keyout relay.pem -x509 -days 365 -out relay.pem
----

// TRANSLATION MISSING
[NOTE]
You must replace `~/.config/weechat` by the path to your WeeChat config directory
which can also be for example `~/.weechat`.

Se WeeChat è già in esecuzione, è possibile ricaricare il certificato e la
chiave privata con il comando:

----
/relay tlscertkey
----

// TRANSLATION MISSING
[[relay_irc_proxy]]
=== Proxy IRC

The Relay plugin can act as an IRC proxy: it will simulate an IRC server, and
you can connect to WeeChat with any other IRC client (including WeeChat itself).

You can define one port by IRC server, or one generic port for all servers.

When using one port for all servers, the client must send the internal name of
server in the IRC "PASS" command, with this format (see example below):

----
PASS server:miapass
----

Example: IRC proxy with TLS for any server (client will choose):

----
/relay add tls.irc 8000
----

Example: IRC proxy without TLS only for server "libera":

----
/relay add irc.libera 8000
----

Now you can connect on port 8000 with any IRC client using server password
"miapass" (or "libera:miapass" if no server was specified in the relay).

For example if you use WeeChat as IRC client of the relay, with a server called
"relay" and the relay password "secret", you can setup the password with these
commands:

----
/secure set relay_libera libera:secret
/set irc.server.relay.password "${sec.data.relay_libera}"
----

// TRANSLATION MISSING
[[relay_api_protocol]]
=== API protocol

The Relay plugin can send data to a remote WeeChat or interface using an
HTTP REST API protocol.

You can browse and test the API online:
https://weechat.org/api/[WeeChat Relay API ^↗^^].

You can connect with WeeChat or a remote interface, see
https://weechat.org/about/interfaces/[this page ^↗^^].

For example:

----
/relay add api 9000
----

Now you can connect on port 9000 with a WeeChat or a remote interface using
password "mypassword".

To connect to an _api_ relay running locally with WeeChat:

----
/remote add weechat http://localhost:9000 -password=mypassword
/remote connect weechat
----

To connect to an _api_ relay running elsewhere with WeeChat
(TLS is highly recommended):

----
/remote add weechat https://example.com:9000 -password=mypassword
/remote connect weechat
----

[NOTE]
The remote WeeChat must expose the same API version as the local WeeChat, so
it's highly recommended to use exactly the same WeeChat version on remote
and local client.

[[relay_weechat_protocol]]
=== Protocollo WeeChat

Il plugin Relay può inviare dati alle interfacce remote usando il protocollo
WeeChat.

// TRANSLATION MISSING
You can connect with a remote interface, see
https://weechat.org/about/interfaces/[this page ^↗^^].

[IMPORTANT]
// TRANSLATION MISSING
WeeChat itself cannot connect to another WeeChat with this protocol.

Ad esempio:

----
/relay add weechat 9500
----

Ora è possibile connettersi sulla porta 9500 con un'interfaccia remota usando la
password "miapass".

// TRANSLATION MISSING
[[relay_websocket]]
=== WebSocket

WebSocket protocol (https://datatracker.ietf.org/doc/html/rfc6455[RFC 6455 ^↗^^])
is supported in Relay plugin for all protocols.

The WebSocket handshake is automatically detected and socket becomes ready for
WebSocket if required headers are found in handshake and if origin is allowed
(see option
<<option_relay.network.websocket_allowed_origins,relay.network.websocket_allowed_origins>>).

A WebSocket can be opened in a HTML5 with a single line of JavaScript:

[source,javascript]
----
websocket = new WebSocket("ws://example.com:9500/weechat");
----

The port (9500 in example) is the port defined in Relay plugin.

The URI must end with "/weechat" for _irc_ and _weechat_ protocols and "/api"
for _api_ protocol.

// TRANSLATION MISSING
[[relay_unix_socket]]
=== UNIX domain sockets

Using the protocol option "unix" with the `/relay add` command, you can listen
using any protocol on a UNIX domain socket at a given path. For example:

----
/relay add unix.weechat ${weechat_runtime_dir}/relay_socket
----

This allows clients to connect using the weechat protocol to
_/run/user/1000/weechat/relay_socket_. This is particularly useful to allow
SSH forwarding for relay clients, when other ports cannot be opened.

Using OpenSSH:

[source,shell]
----
ssh -L 9000:.weechat/relay_socket user@hostname
----

This redirects local relay clients connecting on port 9000 to the WeeChat
instance running on "hostname".

// TRANSLATION MISSING
The FIFO pipe is located in WeeChat runtime directory and is called
_weechat_fifo_12345_ by default (where _12345_ is the WeeChat process id).

La sintassi per i comandi/testo della pipe FIFO è una delle seguenti:

....
  plugin.buffer *testo o comando qui
  *testo o comando qui
....

// TRANSLATION MISSING
Backslashes can be interpreted with this format, where `*` is replaced by `\`,
allowing for example to send multiline messages:

....
  plugin.buffer \text or command here
  \text or command here
....

Alcuni esempi:

// TRANSLATION MISSING
* Change nick on IRC server libera to "newnick":

[[trigger]]
== Trigger

Trigger is the Swiss Army knife for WeeChat: it can hook many things (signal,
modifier, print, ...), change the content of data, and execute one or more
commands. A condition can be used to prevent the trigger to run in some
circumstances.

Using triggers require you to know how the signals, modifiers, ... are working.
So you might consider reading the
link:weechat_plugin_api.it.html#hooks[WeeChat plugin API reference / Hooks ^↗^^].

[[trigger_default]]
=== Default triggers

WeeChat creates 5 triggers by default, which can be disabled, updated or
deleted:

* a _beep_ trigger for notifications
* four other triggers to hide passwords on screen

List of default triggers:

[width="100%",cols="5m,3,22",options="header"]
|===
| Name | Hook | Description

| beep | print
| Beep on highlight/private message.

| cmd_pass | modifier
| Hide password in commands:
  `pass:[/msg nickserv id\|identify\|set password\|ghost\|release\|regain\|recover]`,
  `pass:[/oper]`,
  `pass:[/quote pass]`,
  `pass:[/secure passphrase\|decrypt\|set]`.

| cmd_pass_register | modifier
| Hide password in command `pass:[/msg nickserv register]`.

| msg_auth | modifier
| Hide password in IRC auth message displayed (message received from server
  after the user issued the command).

| server_pass | modifier
| Hide server password in commands `/server` and `/connect`.
|===

[[trigger_anatomy]]
=== Anatomy of a trigger

A trigger has the following options (names are
`trigger.trigger.<name>.<option>`):

[width="100%",cols="2m,3,10",options="header"]
|===
| Option | Values | Description

| enabled | `on`, `off`
| When option is `off`, the trigger is disabled and actions are not executed
  anymore.

| hook | `+signal+`, `+hsignal+`, `+modifier+`, `+line+`, `+print+`, `+command+`,
  `+command_run+`, `+timer+`, `+config+`, `+focus+`, `+info+`, `+info_hashtable+`
| The hook used in trigger. For more information, see
  link:weechat_plugin_api.it.html#hooks[WeeChat plugin API reference / Hooks ^↗^^].

| arguments | string
| The arguments for the hook, it depends on the hook type used.

| conditions | string
| Conditions to execute the trigger; they are evaluated (see command
  <<command_weechat_eval,/eval>>).

| regex | string
| One or more POSIX extended regular expressions, to change data received in the
  hook callback (and some stuff added by trigger plugin), see
  <<trigger_regex,regular expression>>.

| command | string
| Command to execute (many commands can be separated by semicolons); it is
  evaluated (see command <<command_weechat_eval,/eval>>).

| return_code | `+ok+`, `+ok_eat+`, `+error+`
| The return code of callback (default is `ok`, which should be used in almost
  all triggers, the other values are rarely used).

| post_action | `none`, `disable`, `delete`
| Action to take on the trigger after execution (default is `none` which should
  be used in almost all triggers, the other values are rarely used).
|===

For example, the default _beep_ trigger has following options:

----
trigger.trigger.beep.enabled = on
trigger.trigger.beep.hook = print
trigger.trigger.beep.arguments = ""
trigger.trigger.beep.conditions = "${tg_displayed} && (${tg_highlight} || ${tg_msg_pv})"
trigger.trigger.beep.regex = ""
trigger.trigger.beep.command = "/print -beep"
trigger.trigger.beep.return_code = ok
trigger.trigger.beep.post_action = none
----

[[trigger_execution]]
=== Execution

When a trigger callback is called, following actions are executed, in this
order, if triggers are globally enabled and if the trigger itself is enabled:

. check trigger conditions: if false, exit
. replace text in trigger using regular expression(s)
. execute command(s)
. exit with a return code (except for hooks _modifier_, _line_, _focus_,
  _info_ and _info_hashtable_)
. perform post action (if different from `none`).

[[trigger_hook_arguments]]
=== Hook arguments

The arguments depend on the hook used. They are separated by semicolons.

[[trigger_conditions]]
=== Conditions

The conditions are used to continue processing in trigger, or stop everything.

They are evaluated, and data available in callback can be used
(see <<trigger_callback_data,data in callbacks>> and command
<<command_weechat_eval,/eval>>).

Example: the default _beep_ trigger uses this condition to make a beep only on
highlight or private message:

----
${tg_displayed} && (${tg_highlight} || ${tg_msg_pv})
----

[[trigger_regex]]
=== Regular expression

The regular expression is used to change variables in callback hashtable.

Format is one of the following:

----
/string1/string2
/string1/string2/var
s/string1/string2
s/string1/string2/var
y/string1/string2
y/string1/string2/var
----

Fields:

* `s` or `y`: a letter with the command; if missing, default command is `s`
  and the first char is then used as the delimiter:
** `s`: regex replacement: first string is a regular expression, second string
   is the replacement for every matching string
** `y`: chars translation: first string is a set of characters that are replaced
   by the characters in the second string; once evaluated, each string must have
   exactly the same number of UTF-8 chars
* `/`: the regex delimiter; the char "/" can be replaced by any char
  (one or more identical chars)
* `string1`: the first string (use depends on the command)
* `string2`: the second string (use depends on the command)
* `var`: the hashtable variable to update

Many regular expressions can be separated by a space, for example:

----
s/regex1/replace1/var1 y/abcdef/ABDDEF/var2
----

[[trigger_regex_replace]]
==== Regex replace

For the command `s`, the format is: `s/regex/replace` or `s/regex/replace/var`
(where _var_ is a variable of the hashtable).

As `s` is the default command, it can be omitted, so `/regex/replace` is also
valid (but the first char, which is the delimiter, must not be a letter).

Matching groups can be used in _replace_:

* `+${re:0}+` to `+${re:99}+`: `+${re:0}+` is the whole match, `+${re:1}+` to
  `+${re:99}+` are groups captured
* `pass:[${re:+}]`: the last match (with highest number)
* `+${re:#}+`: index of last group captured
* `+${re:repl_index}+`: index of replacement being done (starts to 1)
* `+${hide:c,${re:N}}+`: match "N" with all chars replaced by "c"
  (example: `+${hide:*,${re:2}}+` is the group #2 with all chars replaced by
  `+*+`).

Example: use bold for words between `+*+`:

----
s/\*([^ ]+)\*/*${color:bold}${re:1}${color:-bold}*/
----

Example: default trigger _server_pass_ uses this regular expression to hide
password in commands `/server` and `/connect` (chars in passwords are replaced
by `+*+`):

----
s==^(/(server|connect) .*-(sasl_)?password=)([^ ]+)(.*)==${re:1}${hide:*,${re:4}}${re:5}
----

[NOTE]
In this example, the delimiter used is "==" because there is a "/" in the
regular expression.

[[trigger_regex_translate_chars]]
==== Translate chars

For the command `y`, the format is: `y/chars1/chars2` or `y/chars1/chars2/var`
(where _var_ is a variable of the hashtable).

Example: replace "a", "b" and "c" by upper case letter:

----
y/abc/ABC/
----

Example: rotate arrows clockwise:

----
y/←↑→↓/↑→↓←/
----

Example: convert all letters to lower case:

----
y/${chars:upper}/${chars:lower}/
----

Example: shift each letter by one position, preserving case: a→b, b→c … y→z, z→a:

----
y/${chars:a-z}${chars:A-Z}/${chars:b-z}a${chars:B-Z}A/
----

[[trigger_regex_variable]]
==== Variable

If _var_ does not exist in the hashtable, it is created automatically with an
empty value. This allows to create custom temporary variables.

If _var_ is not specified, the default variable is used, it depends on hook
type:

[width="100%",cols="2,3,7",options="header"]
|===
| Hook           | Default variable   | Update allowed ^(1)^
| signal         | tg_signal_data     |
| hsignal        |                    |
| modifier       | tg_string          | tg_string
| line           | message            | buffer, buffer_name, id, y, date, date_usec, str_time, tags, notify_level, highlight, prefix, message
| print          | tg_message         |
| command        | tg_argv_eol1       |
| command_run    | tg_command         |
| timer          | tg_remaining_calls |
| config         | tg_value           |
| focus          |                    |
| info           | tg_info            | tg_info
| info_hashtable |                    | all variables received in hashtable
|===

[NOTE]
^(1)^ All variables can be updated in the trigger, but only these variables
have an effect on the value returned by the trigger and used by WeeChat.

[[trigger_command]]
=== Command

The command is executed after replacement of text with the regular expression.
Many commands can be separated by semicolons.

It is evaluated (see command <<command_weechat_eval,/eval>>) and text replaced
with a regular expression can be used in the command.

Example: default _beep_ trigger uses this command to make a beep (BEL):

----
/print -beep
----

[[trigger_callback_data]]
=== Data in callbacks

Data received in callbacks are stored in hashtables (pointers and strings) and
can be used in following options:

* _conditions_
* _regex_
* _command_

The content of hashtables depend on the hook type.

A convenient way to see data in a trigger is to open trigger monitor buffer,
using the command:

----
/trigger monitor
----

All callbacks set following variables in hashtable:

[width="100%",cols="3m,2,14",options="header"]
|===
| Variable        | Type   | Description

|===

// TRANSLATION MISSING
[NOTE]
^(1)^ The nick is the sender of the message. +
Your own nick on the server is `${irc_server.nick}`.

When the data is a pointer, the variable `+tg_signal_data+` can be used like this
to read a hdata property (in this example this is a pointer on a buffer):

----
${buffer[${tg_signal_data}].full_name}

[[trigger_examples]]
=== Examples

[[trigger_example_url_color]]
==== Color for URLs

Display URLs in green:

----
/trigger add url_color modifier weechat_print "${tg_notify}" "==[a-zA-Z0-9_]+://[^ ]+==${color:green}${re:0}${color:reset}=="
----

[NOTE]
The simple regex used to detect URL may not catch well all URLs, but it is
faster than a complex regex.

[[trigger_example_auto_pong]]
==== Auto pong on ping queries

When someone sends a "ping" in a private buffer, this trigger will auto-reply
with `pong`:

----
/trigger add pong print "" "${type} == private && ${tg_message} == ping" "" "pong"
----

[[trigger_example_responsive_layout]]
==== Responsive layout

Following triggers can be used to customize things displayed when the size of
terminal is changed:

----
/trigger add resize_small signal signal_sigwinch "${info:term_width} < 100" "" "/bar hide nicklist"
/trigger add resize_big signal signal_sigwinch "${info:term_width} >= 100" "" "/bar show nicklist"
----

The triggers catch the signal "signal_sigwinch", which is sent by WeeChat when
signal SIGWINCH is received (when terminal size is changed).

The condition with `+${info:term_width}+` checks the width of terminal (you can
also use `+${info:term_height}+` if needed).

In the example, when the terminal becomes small, the nicklist is hidden. And the
bar is restored when the width is greater or equal to 100 chars.

[[trigger_example_config_save]]
==== Automatic save of configuration

You can automatically save configuration files (`+*.conf+`), for example each
hour:

----
/trigger add cfgsave timer 3600000;0;0 "" "" "/mute /save"
----

Arguments for the timer hook are:

* _3600000_: 3600 * 1000 milliseconds, the callback is called each hour
* _0_: alignment on second (not aligned here)
* _0_: max number of calls (0 = no end for the timer)

The command `/mute /save` will silently save configuration files (nothing
displayed on core buffer).

[[extending_weechat]]
== Extending WeeChat

// TRANSLATION MISSING
WeeChat has a modular design and can be extended with plugins and scripts.

È importante evidenziare la differenza tra un _plugin_ ed uno _script_: un
_plugin_ è un file binario compilato e caricato con il comando `/plugin`,
mentre uno _script_ è un file di testo caricato con un plugin come _python_
con il comando `/python`.

[[plugins]]
=== Plugin

Un plugin è una libreria dinamica, scritta in C e compilata, che viene caricata
da WeeChat.
In GNU/Linux, il file ha estensione ".so", ".dll" in Windows.

I plugin trovati vengono caricati automaticamente all'avvio di WeeChat, ed
è possibile caricare o scaricare i plugin durante l'esecuzione del programma.

È possibile utilizzare il comando `/plugin` per caricare/scaricare un plugin,
oppure elencare tutti i plugin caricati.

// TRANSLATION MISSING
When a plugin is unloaded, WeeChat removes:

* buffers
* configuration options (options are written in files)
* all hooks: commands, modifiers, process, etc.
* infos and infolists
* hdata
* bar items.

Esempi per caricare, scaricare oppure elencare i plugin:

----
/plugin load irc
/plugin unload irc
/plugin list
----

I plugin predefiniti sono:

Per saperne di più riguardo lo sviluppo di plugin o script (tramite le API), per
favore consultare link:weechat_plugin_api.it.html[Riferimento API dei Plugin per WeeChat ^↗^^]
oppure link:weechat_scripting.it.html[Guida allo Scripting di WeeChat ^↗^^].

// TRANSLATION MISSING
[[scripts]]
=== Scripts

WeeChat fornisce 8 plugin per lo scripting: Python, Perl, Ruby, Lua, Tcl, Guile
(scheme), JavaScript, PHP.
Questi plugin possono caricare, eseguire e scaricare gli script per questi
linguaggi.

Per maggiori informazioni su come scrivere gli script, o le API WeeChat
per gli script, consultare la link:weechat_scripting.it.html[Guida allo Scripting di WeeChat ^↗^^].

// TRANSLATION MISSING
[[script_manager]]
==== Script manager

// TRANSLATION MISSING
The script manager (command <<command_script_script,/script>>) is used to
load/unload scripts of any language, and install/remove scripts of WeeChat
scripts repository, which are visible on
https://weechat.org/scripts/[this page ^↗^^].

// TRANSLATION MISSING
For privacy considerations, the download of scripts is disabled by default. +
To enable it, type this command:

----
/script enable
----

// TRANSLATION MISSING
Then you can download the list of scripts and display them in a new buffer
with the <<command_script_script,/script>> command:
